Abstract

Provided is a PCV valve assembly that includes a fluidic geometry that allows for the flow of combustion fluid/gas to flow between an inlet and an outlet and switch between two modes of operation, (i) a radial or high flow mode, and (ii) a tangential or low flow mode, as dictated during the operation of the engine. At low vacuums, the fluidic equipped PCV valve assembly has been tuned to operate in the radial mode producing high flow rates due to low flow resistance. As vacuum increases, the PCV valve assembly is tuned to automatically switch modes. This may be enabled due to the shape of the fluidic geometry and the bypass channel which is adapted to vary the amount of flow between a first and a second control ports. The bypass channel allows the geometric fluidic pattern to switch between the high flow mode and the low flow mode.
